RIP Version

The RIP Version field controls the format and the broadcasting method of the

 

 

 

RIP packets that the Prestige sends (it recognizes both formats when

 

 

 

receiving).

 

 

 

Choose RIP-1,RIP-2B or RIP-2M.

 

 

 

RIP-1is universally supported; but RIP-2carries more information. RIP-1 is

 

 

 

probably adequate for most networks, unless you have an unusual network

 

 

 

topology. Both RIP-2Band RIP-2Msends the routing data in RIP-2 format; the

 

 

 

difference being that RIP-2B uses subnet broadcasting while RIP-2M uses

 

 

 

multicasting. Multicasting can reduce the load on non-router machines since

 

 

 

they generally do not listen to the RIP multicast address and so will not receive

 

 

 

the RIP packets. However, if one router uses multicasting, then all routers on

 

 

 

your network must use multicasting, also. By default, the RIP Version field is

 

 

 

set to RIP-1.

 

 

Multicast

Choose None (default), IGMP-V1or IGMP-V2. IGMP (Internet Group Multicast

 

 

 

Protocol) is a network-layer protocol used to establish membership in a

 

 

 

Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236)

 

 

 

is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in

 

 

 

wide use. If you would like to read more detailed information about

 

 

 

interoperability between IGMP version 2 and version 1, please see sections 4

 

 

 

and 5 of RFC 2236.

 

 

Windows Networking (NetBIOS over TCP/IP):

 

 

NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets that enable a

 

 

computer to connect to and communicate with a LAN. For some dial-up services such as PPPoE,

 

 

NetBIOS packets cause unwanted calls. However it may sometimes be necessary to allow NetBIOS

 

 

packets to pass through to the WAN in order to find a computer on the WAN.

 

 

Allow between LAN

Select this check box to forward NetBIOS packets from the LAN to the WAN

 

 

and WAN

and from the WAN to the LAN.

 

 

 

Clear this check box to block all NetBIOS packets going from the LAN to the

 

 

 

WAN and from the WAN to the LAN.

 

 

 

You also need to configure a firewall rule that allows NetBIOS traffic to pass

 

 

 

from the WAN to the LAN.

 

 

Allow Trigger Dial

Select this option to allow NetBIOS packets to initiate calls.
